A slightly lighter task that doesn t unnecessarily copy files to a dir  task downloadDependencies type  Exec        configurations testRuntime files     commandLine  echo    Downloaded all dependencies     Updated for kotlin  amp  gradle 6 2 0  with buildscript dependency resolution added  fun Configuration isDeprecated     this is DeprecatableConfiguration  amp  amp  resolutionAlternatives    null  fun ConfigurationContainer resolveAll     this    filter   it isCanBeResolved  amp  amp   it isDeprecated        forEach   it resolve      tasks register  quot downloadDependencies quot       doLast       configurations resolveAll       buildscript configurations resolveAll

This version builds on Robert Elliot s  but I m not 100  sure of its efficacy      There are a few dependencies added by one of the Scala plugins that this cannot reach  task downloadDependencies     description  Pre-downloads  most  dependencies    doLast       configurations getAsMap   each   name  config - gt        println  Retrieving dependencies for  name        try           config files         catch  e            project logger info e message    some cannot be resolved  silentlyish skip them                       I tried putting it into configuration instead of action  by removing doLast  and it broke zinc  I worked around it  but the end result was the same with or without  So  I left it as an explicit state  It seems to work enough to reduce the dependencies that have to be downloaded later  but not eliminate them in my case  I think one of the Scala plugins adds dependencies later

It is hard to figure out exactly what you are trying to do from the question  I ll take a guess and say that you want to add an extra compile task in addition to those provided out of the box by the java plugin   The easiest way to do this is probably to specify a new sourceSet called  speedTest   This will generate a configuration called  speedTest  which you can use to specify your dependencies within a dependencies block  It will also generate a task called compileSpeedTestJava for you   For an example  take a look at defining new source sets in the Java plugin documentation  In general it seems that you have some incorrect assumptions about how dependency management works with Gradle  I would echo the advice of the others to read the  Dependency Management  chapters of the user guide again

Downloading java dependencies is possible  if you actually really need to download them into a folder   Example   apply plugin   java   dependencies     runtime group   com netflix exhibitor   name   exhibitor-standalone   version   1 5 2    runtime group   org apache zookeeper    name   zookeeper   version   3 4 6     repositories   mavenCentral      task getDeps type  Copy      from sourceSets main runtimeClasspath   into  runtime       Download the dependencies  and their dependencies  into the folder runtime when you execute gradle getDeps

You should try this one    task getDeps type  Copy        from configurations runtime     into  runtime       I was was looking for it some time ago when working on a project in which we had to download all dependencies into current working directory at some point in our provisioning script  I guess you re trying to achieve something similar

There is no task to download dependencies  they are downloaded on demand  To learn how to manage dependencies with Gradle  see  Chapter 8  Dependency Management Basics  in the Gradle User Guide
